ID code: '3CGS' CHIRALITY (03 Nov 1998) Checks the chirality and the naming of substituents of chiral and prochiral centers in nucleic acid structures. The molecular structure is read from a PDB file. Only the first model is evaluated. ---------------------------------------------------------- Center Reference for correct naming ---------------------------------------------------------- C1' alpha/beta nomenclature of anomeric sugars, base in beta position in natural nucleosids.
